The soybean market saw a notable 4% decline on the Chicago Stock Exchange, leading to significant drops in the grains market, including corn, wheat, and soybean products. August and November soybean contracts closed at $10.71 and $10.46 per bushel, respectively. This decline was driven by several factors: a new waiver for small refineries from the US Supreme Court, falling oil prices, improved climate models for the American Midwest, worsening crushing margins in China, and increased Malaysian palm oil exports reducing demand for soybean oil.
